Improve the performance of your 2021+ BMW G8X M2/M3/M4 with the do88 Front Intercooler Radiator, a radiator designed for optimal charge air cooling under demanding driving conditions.

Background
The S58 engine have a water-to-air charge cooler paired with a heat exchanger (water radiator) in the front of the car. This radiator cool the water flowing through the charge air cooler, the water dissipate heat from the charge air before it enters the engine.

Challenges of the S58 Charge Air Cooling System
Owners of tuned S58 engines often encounter the problem of rapid Heat-Soak in the charge air cooling system, especially during track driving. High intake temperatures can cause the ECU to reduce power output, or even put the car into limp mode. The do88 Front Intercooler Radiator helps to keep temperatures down and improve your car's reliability and performance.

Our Solution
The custom do88 radiator design began with a total overhaul, prioritizing durability and performance. By eliminating plastic components in favor of sturdy aluminum for the end tanks, the core, and CNC-machined ports, and ensuring everything is TIG-welded, our cooler provides durability and long-term performance. The introduction of a Quad pass design improves cooling, with the coolant passing through the cooler's core four times for maximum efficiency.

But do88's goal extends beyond just durability. By increasing the core volume by 39% and the external tube area by 9%, while simultaneously integrating a Quad pass flow for the coolant, the do88 cooler go beyond the original. This results in improved cooling capacity, thereby enhancing your car's performance.

Installation
The do88 cooler is designed to be easily mounted with your BMW's factory components. It comes with custom rock guards to protect against debris. Our cooler fits both cars with automatic or manual transmissions, making it a versatile upgrade for all G8X M2/M3/M4 models.

Key Features:

• 39% larger core than original.
• 2-row core that is 48mm thick, this provides an increased active cooling area by a whole 9%.
• Quadruple-pass flow, this allows the water to pass through the cooler four times instead of two as on the original cooler, ensuring that one maximizes the waters contact with the cooling area.
• Slightly higher cooling fins compared to original, 5mm instead of 4.4 mm. This ensuring good airflow to the engine radiator despite the increased core thickness.
• Full aluminum construction, complete with durable TIG-welded end tanks.
• Increased fluid capacity (1,4 liter more) for optimal heat dissipation.

Upgrade your BMW G8X M2/M3/M4 with our do88 radiator and unlock improved cooling efficiency and performance under demanding driving conditions.
